Re: Frankenso going limp at 6,000 RPM.

A different and not-so-important question: the LCD is too bright, and can be read only from an angle. I'm using the hd44780 setting on it. Is there a setting that I can change to make it readable? I can post a picture tomorrow if needed. There should be a tiny potentiometer you can adjust with a sm...

Re: Frankenso going limp at 6,000 RPM.

A log file would help Maybe your injector duty cycle reaches 100%? That would be visible in the logs. Thanks, @AndreyB! I can try and get a TunerStudio log file tomorrow. I ran a quick test with logging enabled in TunerStudio. My test consists of step increases in the engine rpm by 500 every 10 sec...

Frankenso going limp at 6,000 RPM.

Hi all, I have a Frankenso ECU that I'm using in a Hardware-in-Loop rig. I am using a custom 58/2 trigger signal. Things work beautifully until I hit 6,000 RPM on the crank signal. At exactly 6,000 RPM though, the ECU shuts ignitions and injections down and goes limp. I don't remember it behaving th...

Re: Settings configuration error: VSS already configured.

Thanks, @mck1117 and @AndreyB. But I have the Joystick pins already disabled (center, button A, B, C, D all set to NONE).

I can try to use the latest build from 2021.09.20 to see if that resolves the issue.

Malfunctioning Frankenso board.

Hello fellow rusEFI-ers, BLOT I have a Frankenso-based ECU (~3-4 years old) that I have built a Hardware-in-loop rig with. Of late, some of the pins on the board are acting as 5V outputs when they should not be. Details I have a Frankenso-board ECU that some of you may recognize (photo attached: Fra...
